We look at the division of 73448402 by 253 
We want to figure out the number of times 73448402 can be divided by 253.

Let's proceed to step 1:
253 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 253

On to step 2:
When dividing 73 by 253, we get 0 with a remainder of 73.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 73 and we're left with 73.
Include the next digit (4) from the dividend after 73, then repeat: 734 / 253

Moving on to step 3:
253 goes into 734 2 times with a remainder of 228.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 506 from 734, we get 228.
Grab the next digit (4) from the dividend, add it to 228, then carry on: 2284 / 253

Step 4:
253 goes into 2284 9 times with a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 29.0
Deduct 2277 from 2284 and we're left with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 253

Let's proceed to step 5:
253 can be fit into 78 0 times, resulting in a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 290.0
Subtract 0 from 78 to get 78.
Take the next digit (4) from the dividend and append it to 78, then repeat: 784 / 253

Moving on to step 6:
253 goes into 784 3 times with a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 2903.0
Deduct 759 from 784 and we're left with 25.
Take the next digit (0) from the dividend and append it to 25, then repeat: 250 / 253

Moving on to step 7:
If we divide 250 by 253, we get 0 and a remainder of 250.
The next digit of our result is 0. 
Result so far: 29030.0
Deduct 0 from 250 and we're left with 250.
Take the next digit (2) from the dividend and append it to 250, then repeat: 2502 / 253

Let's proceed to step 8:
2502 divided by 253 is 9 with a remainder of 225.
Record the quotient 9 as the next digit in the result. 
Result so far: 290309.0
Subtract 2277 from 2502 to get 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Advancing to step 9:
When dividing 2250 by 253, we get 8 with a remainder of 226.
Use 8 as the next digit of our solution. 
Result so far: 290309.8
If we subtract 2024 from 2250, we get 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Let's proceed to step 10:
If we divide 2260 by 253, we get 8 and a remainder of 236.
Record the quotient 8 as the next digit in the result. 
Result so far: 290309.88
Subtract 2024 from 2260 to get 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

The final outcome is 290309.88, with a leftover of 0.236.
